Title:
H11997OUTLINE: Outline of the Bathymetric Data Collected During National Oceanic and Atmospheric Administration (NOAA) Survey H11997 (Geographic, WGS84)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth survey see <http://quashnet.er.usgs.gov/data/2010/10015/>

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 2)
    The GeoTIFF image of the multibeam bathymetry from NOAA survey H11997 was imported into the ArcView 3.3 GIS project view. These acoustic data were outlined using the available graphic tools then converted to a polygon shapefile using ArcView 3.3.

    Date: 2010 (process 2 of 2)
    ArcGIS 9.2 was used to define the projection as geographic WGS84 of the ESRI shapefile and to create the .prj file using the ArcToolbox Define Projection tool. XTools was used to calculate the area based on UTM Zone 18, WGS84 (UTM to get a more accurate area and WGS84 so the data were not reprojected during the calculation).
